IMPROVEMENT IN WICK-TUBES.y

Specification forming part of Letters Patent No. 207,614, datedSeptember 3, 1878; application ilcd July 9, 1877.'

To all whom it may concern:

Be it known that I, HUGH MCGONNELL, of Cleveland, county of Cuyahoga,and State of Ohio, have invented certain new and useful Improvements inWick-Tubes and I do hereby declare the following to be a full, clear,and exact description of the invention, such. as will enable othersskilled in the art to which it pertains to make and use it, referencebeing had to the accompanying drawings, which form a part of thisspecification.

My invention relates to certain improvements in wick-tubes, and isdesigned especially for use in oil-stoves, though it is also applicablefor use in all cases where wick-tubes are employed.

The invention consists in a wick tube formed of t-wo pieces of sheetmetal, folded one around the other at the edges, and one of said piecesprovided with a feed wheel housing struck out upon its side from thesolid, so as to form said housing without joint.

In the drawings, Figure l represents my-invention applied as in use toan oilstove. Fig. 2 is aview, in side elevation, of the same, with theupper body of the stove removed. Fig. 3 is a detail perspective view ofthe wicktube. Fig. 4 is a vertical cross-sectional view of the same.Fig. 5 is a horizontal sectional view through line x y of Fig. 3. Fig. 6is a sectional side elevation of the tube.

The wick-.tube A is formed with the two pieces a b of sheet metal foldedone around the other at the edges, as shown atc. One of said pieces, a,is provided with a suitable feed-wheel housing, d, struck out upon itsside from the solid, and forming a housing without joint.

A wick-tube thus constructed of two pieces, with the edges of one piecemade to overlap and embrace the edges of the other, and with thefeed-wheel housings struck up from the solid metal forming one of thepieces, will not separate and become distorted, even though the tubeshould become so hot as to melt all the solder along the whole tube;whereas, if the edges were simply lapped against each other and thensoldered, they would be dropped apartby unsolderin g, and might, byderanging the action of the lamp, cause the iiame to descend along theexposed wick and communicate with the oil beneath; so, also, the samething might occur if there was any soldered joint either at the ends,the sides, or across the body of the feed-wheel housings; besides, inthe latter case, the wick-feeding mechanism might be renderedinoperative.

In the drawings, I have represented the wick-tube A as applied to anoil-stove having an oil-reservoir, B, consisting preferably of an uppercast plate of metal, having upon its inner lower rim an annularshoulder, C. Within the enlarged chamber formed by said shoulder thebottom plate D is placed. All these parts, before being united, shouldbe galvanized, after which the bottom plate is soldered in place uponsaid annular shoulder, thus forming a reservoir having a galvanizedinterior in a cheap, reliable, and effective manner. The feed-openin g Eofthe reservoir is formed raised from the surface of the reservoir,thereby allowing the removal of the cap F from the reservoir when thelatter is filled with oil without liability of any escape of the latter.This feed-opening can also be used for purposes of removing andreplacing the wicks should they by any cause fall below the wickfecdingapparatus.

A perforated plate or diaphragm, G, is interposed between theoil-reservoir and the top ofthe wick-tubes.

The body of the stove H is provided with feet h, which rest in suitableseats formed on the reservoir, while within the stove-body a ventilatedseat, K, is placed, upon which the chimneys L rest. These chimneys areheld in a frame provided with a handle, whereby they may be readilyplaced in position or removed, as desired, any suitable door beingprovided in the stove-body adapted to permit of such movement.

A removable top, M, designed to support suitable culinary implements, isformed with bearing points or projections m, which permit of draft,while the full action of the heat yupon said implements is not impeded.

I desire to be understood as laying no claim in this patent to theoil-stove shown and described herein, and I reserve my right tohereafter le t separate application for Letters Patent embracing suchsubject-metter.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is`

A Wick-tube formed of two pieces of sheet metal, folded one around theother at the edges, :ind one of said pieces provided with the feed-Wheel housing struck out upon its side from the solid, so as to form thehousing without joint, substantially as and for the purposes described.

In testimony whereof I have signed my naine to this specification in thepresence of two subscribing,` Witnesses.

HUGH MGCONNELL.
